Start Slow – Growcraft lights have VERY high light output and unless your plants are already acclimated to high light intensity, it is best to start slow with the light hanging high and possibly also dimmed. Then monitor plant reaction over a few days and slowly adjust as needed.

    I ordered this for my 4×2 as a tester of yalls product quality. I was simply blown away the light intensity and efficiency is insane. It went together quickly and stays very cool compared to all other lights I’ve used.

    First and foremost – Customer Service was AMAZING! I initially emailed on a Sunday with a question about availability, not expecting to get a response until Monday….but nope…1 hour later I had a quick response, and immediately purchased my light! Quality of the light kit was also top notch – Light output is absolutely incredible too. I can’t speak highly enough about ChilLED as a company! Don’t waste your money with another ‘budget’ light…just do it and go with ChilLED!

    One of the best lights out there, hands down! I ran a comparison grow out of two tents with the same size light and ChilLED outperformed in size and density on the flowers. Heavy and dense is the two words which best describes my harvest. The lights will put your tent in beast mode.

    • Gabrielle

      That is amazing Michael! Thanks for letting us know about your growing experience.
